stl 中的map容器，确立了一对一的关系；

#include <iostream>
#include <string>
#include <map>
using namespace std;
string words,temp;
map < string , string > mp;
int main ()
{
cin >> words;
while ( cin >> words, words != "END" )
{
cin >> temp;
mp[ temp ] = words;
}
cin >> words;
cin.get();
while ( getline ( cin, words ) && words != "END" )
{
string out = "";
int len = words.size();
for ( int i = 0; i != len; ++ i )
{
if ( isalpha ( words[i] ) )
{
out += words[i];
}
else
{
if ( mp[out] == "" )
cout << out;
else
cout << mp[out];
cout << words[i];
out = "";
}
}
cout << endl;
}
return 0;
}
